Need Help. Setting up Mobile internet on Samsung Galaxy Pro B7510

I've been at this since yesterday morning. I can't get my mobile internet set up. I got the settings from 2951 and installed them but my default browser just won't connect. I'm running a 2.3 gingerbread OS. The phone is brand new so I didn't mess with the settings too much yet. I really need help coz I already registered for globe super surf 50 on my postpaid. >.> This is really frustrating.
